Kai Store is a small family business located about a block away from the KTA on Puainako Street. It is a laid-back, mom & pop place with an old town feel. The store offers a small selection of convenient store items and is a good spot to explore for Big Island omiyage. They are known for locally made things like One Ton Chips, taro chips, and sweet potato chips, available at great prices. They also sell dried fish like aku and ahi, jerky, and smoked fish, with products that look fresh. Some find their taro chips harder than others, but it is a nice place to patronize and support. For those looking for these specific local goods, it is a must stop in Hilo.
